Re: bad install
To me it looks like a beam clamp that is rated for 500 kg overhead, a quick link that is rated for 400-800 kg overhead, four wires rated at 200-250 kg. It doesn't look like climbing gear, and why on earth would anyone use a piece of climbing gear in amongst stuff that is obviously sourced from the right place? As far as I know you don't get beam clamps and steel wire in sports shop.
I don't know if anything is fastened right and that the wire is assembled right or anything like that, but we are talking about a SWL of twenty times the weight of the speaker here. If this isn't good enough, what is?
If we assume that it is not assembled right, than we can assume that everything we come across is faulty. While that is a fair assumption to make if we are handling or moving the stuff or in anyway interfering with, loading it extra or indeed inspecting, it is not a fair assumption to make based on pure speculation about the possible incompetence of whoever installed the system.
